description FIELD: technological processes.SUBSTANCE: red mud is ground and separated by magnetic separation into magnetic and non-magnetic fractions. Before grinding, red muds are mixed with water activated by the magnetic field to the state of the pulp. To grind the mud, a pulp flow is formed and passed through a "boiling bed" of ferromagnets, which is acted upon by a rotating magnetic field. The frequency of the rotation of the magnetic field is changed until cavitation in the pulp flow occurs at the resonance of the ferromagnets oscillations with the self-oscillations of the pulp particles in the frequency range 14-25 khz with the destruction of the solid pulp fractions into the constituent finely divided elements. After that, they are sent to a magnetic separation to separate into types, and water is removed for a subsequent cycle.EFFECT: reduces power consumption.1 cl Изобретение относится к переработке красных шламов - отходов алюминиевого производства. Красный шлам измельчают и разделяют с помощью магнитной сепарации на магнитную и немагнитную фракции. Перед измельчением красные шламы смешивают с активированной магнитным полем водой до состояния пульпы. Для измельчения шлама формируют поток пульпы и пропускают его через «кипящий слой» ферромагнетиков, на который воздействуют вращающимся магнитным полем. Частоту вращения магнитного поля изменяют до появления в потоке пульпы кавитации при резонансе колебаний ферромагнетиков с собственными колебаниями частиц пульпы в диапазоне частот 14-25 кГц с разрушением твердых фракций пульпы на составляющие мелкодисперсные элементы. После этого их отправляют на магнитную сепарацию для разделения на виды, а воду отводят для последующего цикла. Техническим результатом является переработка шлама с наименьшим энергопотреблением.
